<h4 class="subsection">9.27.11 Directives to save and restore options</h4>

<a name="index-MIPS-option-stack"></a>
<a name="index-_002eset-push"></a>
<a name="index-_002eset-pop"></a>
<p>The directives <code>.set push</code> and <code>.set pop</code> may be used to save
and restore the current settings for all the options which are
controlled by <code>.set</code>.  The <code>.set push</code> directive saves the
current settings on a stack.  The <code>.set pop</code> directive pops the
stack and restores the settings.
</p>
<p>These directives can be useful inside an macro which must change an
option such as the ISA level or instruction reordering but does not want
to change the state of the code which invoked the macro.
</p>
<p>Traditional MIPS assemblers do not support these directives.
